Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655272, here are decompositions:

13 + 8655259 = 8655272
61 + 8655211 = 8655272
313 + 8654959 = 8655272
331 + 8654941 = 8655272
433 + 8654839 = 8655272
463 + 8654809 = 8655272
499 + 8654773 = 8655272
523 + 8654749 = 8655272

Showing the first eight; more decompositions exist.
